    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer electrolyte fuel cells; PEMFC; AEMFC; bipolar plates; corrosion; poly arylene piperidinium ; ionomer; electrode structure; silver nanoparticles; oxygen reduction reaction; Polymerelektrolytbränsleceller; PEMFC; AEMFC; bipolära plattor; korrosion; poly arylenpiperidinium ; jonomer; elektrodstruktur; silvernanopartiklar; syrgasreduktionsreaktion; Chemical Engineering; Kemiteknik;

    Abstract : Polymer electrolyte fuel cells occupy a key position in implementing the hydrogen economy on a global scale. However, assessments of cost, availability and sustainability of materials currently used to manufacture state-of-the-art fuel cell stacks have given cause for concern. READ MORE

  4. 22. Development and validation of a system for the generation, characterization and subsequent air- liquid interface studies of aerosol particles

    Author : Christian Svensson; Ergonomi och aerosolteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoparticles; aggregates; aerosol; protein interactions; toxicology; dose; air liquid interface;

    Abstract : Exposure to nano-sized and nanostructured aerosol particles with tailored properties are likely to increase in society. Occupational exposure to various kinds of nanostructured aerosol particles such as soot and metal aggregates already exists. READ MORE

  5. 23. Coated Surfaces for Inkjet-Printed Conductors

    Author : Thomas Öhlund; Hans-Erik Nilsson; Jonas Örtegren; Jouko Peltonen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet; Nanoparticles; Paper; Flexible substrates; Sintering; Printed Electronics; Functional Printing;

    Abstract : In this thesis, a number of commercially available paper substrates of various types are characterized and their characteristics related to the performance of inkjet-printed conductors using silver nanoparticle ink. The evaluated performance variables are electrical conductivity as well as the minimum achievable conductor width and the edge raggedness. READ MORE

  6. 24. Free Metal Clusters Studied by Photoelectron Spectroscopy

    Author : Tomas Andersson; Olle Björneholm; Maxim Tchaplyguine; Paolo Piseri; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; clusters; nanoparticles; electronic structure; photoelectron spectroscopy; synchrotron radiation; surface segregation; nanoalloys; size-dependence; metallicity; plasmons; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Clusters are aggregates of a finite number of atoms or molecules. In the present work, free clusters out of metallic parent materials have been created and studied by synchrotron radiation-based photoelectron spectroscopy. The clusters have been formed and studied in a beam and the electronic structure of the clusters has been investigated. READ MORE

  7. 25. Plasmonics with a Twist

    Author : Robin Ogier; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasmonic nanostructures; colloidal lithography; particle spinning; optical tweezers; nanofabrication; nanoparticles; chirality;

    Abstract : This thesis focuses on the exploration of interactions between circularly polarized light and plasmonic nanostructures, and nanoparticles. Polarization is an integral part of light and has a wealth of applications in the modern world. READ MORE
